Six Sigma is fundamentally a set of tools to address problems of process quality and consistency. This increase in performance and decrease in process variation leads to waste reduction and improvement in revenues, frees up cash flow, and increases profitability and employee satisfaction. Six Sigma is synonymous with the DMAIC (Define, Measure, Analyze, Improve, and Control) methodology and its associated tool kit.
The DMAIC methodology provides a structured framework for solving business problems by assuring correct and effective process execution. DMAIC entails defining a problem precisely, measuring to bound and clarify it, analyzing the business process associated with the problem to identify the problem's root cause, improving the process by considering alternative solutions and selecting and implementing the best one, and controlling the process through ongoing measurement to ensure that the problem does not recur. The tools brought to bear in the context of applying DMAIC range from process control charts to measurement systems analysis.
Six Sigma’s tools focus laser-like on-process control and process consistency, and in the framework, Six Sigma provides powerful tools to drive process improvement. However, while Six Sigma can isolate and solve problems within a framework, it is powerless to create an alternative framework. That is the role of another business improvement regime, or process redesign. Thomas Group applies its vast body of process management knowledge, experience, and tools, including classic Six Sigma tools, to drive measurable results. Three kinds of implementations include:
Six Sigma is a toolset designed to quantify the elements of customer value and reduce variability in process output. Six Sigma is highly data intensive, and best applied to problems that are characterized by fairly high transaction volume and good data fidelity where its statistical rigor can be put to best use. With Thomas Group's proven Process Value Management methodology, Six Sigma tools can be directed to areas where they are most applicable, while simultaneously attacking root cause cultural barriers.
